OKLAHOMA CITY (AP) — A storm that rolled through central Oklahoma has left thousands without power from southwestern Oklahoma to western Arkansas, spawned a possible tornado and led to about a dozen high-water rescues.

National Weather Service meteorologist Bruce Thoren said investigators on Tuesday were reviewing damage from a possible tornado Monday night in Logan County, about 20 miles (32 kilometers) north of downtown Oklahoma City.

Trees were down across Oklahoma City, where Oklahoma Gas & Electric reported about 46,000 outages. More than 86,000 OG&E and Public Service Company of Oklahoma customers were without electricity from the Lawton area to the Fort Smith, Arkansas, area. Some Oklahoma schools without power closed Tuesday.

Oklahoma City Fire Capt. David Macy said firefighters rescued about a dozen motorists and a fisherman from below a dam at an Oklahoma City lake where he had been trapped by rising waters.
